I will fix bugs in your node js script or API integration
Evgenii
About this gig
Your Node.js script or API integration throws errors, returns wrong data or stopped working? I will find the cause and fix it.
What you get:
- Diagnosis: what exactly is broken and why
- The fix in your code, with a short explanation of what I changed
- A quick check that the problem is gone
- Notes on how to avoid the same error in the future
Works well for: API errors (401, 403, 429, 5xx), wrong or missing data, crashes, timeouts, async/await and promise problems, payment and exchange API integrations, scripts that stopped working after an update.
Before you order, send me a message with the code (or the relevant part) and the error. I will tell you if I can help. If the task is outside what I can do well, I will say so before you pay.
Please never send live passwords, API secrets or private keys. Replace them with fake values.

I build Node.js tools around APIs: Telegram bots, payment integrations (PayPal Orders API), crypto market data scripts and alerts, and honest backtests of trading ideas. I write clean code with automated tests and clear setup instructions. Recent open projects: CartGuard, an AI shopping agent with PayPal and a rule engine (github.com/Woligin/cartguard), and an AI FAQ Telegram bot (github.com/Woligin/ai-faq-telegram-bot). I work in writing only, agree the scope before starting, and tell you upfront if a task is outside what I can do well.

Node.js and JavaScript. For other languages, please ask me first.
